With temperatures expected to feel like triple digits for the rest of the week, the NBC10 First Alert Weather Team issued a First Alert for Philadelphia and the immediate suburbs through Friday afternoon.
People should plan on limiting outdoor activity as temps push into the upper 90s Thursday and Friday afternoon as the area enters a heat wave (three straight days of highs of 90 degrees or more).
Poor air quality and humidity could cause difficulties for people with respiratory problems as the heat index hits 100 degrees or more (highs are expected to hit 97 both days with a feel-like temp of 104). The Excessive Heat warning covers Philadelphia, Wilmington and Trenton as well as parts of South Jersey, Delaware County, Montgomery County, Chester County and Bucks County.
"Temperatures will be running around 10 degrees above normal, and it’s this hot humid weather pattern that’s causing poor air quality," said NBC10 First Alert Weather meteorologist Sheena Parveen.
Besides the hot, hazy conditions, a thunderstorm could strike both Thursday and Friday.
After another day in the 90s Saturday, temps finally cool off Sunday as temps will only reach the 80s.
